- What follows is a summary of how to recover your SVR4.2 system from the
- boot floppies. Note that this is for the USL reference binary and has not
- been tried on UNIXware or Concensys V4.2.
-
- Here's how to recover:
-
- (1) Insert boot floppy1 and bring your system up, then Insert boot
- floppy2 as prompted.
-
- (2) Go through fdisk(1M) without changing your partitions allocation.
- (i.e. type "5" for exit at the screen asking you whether to create
- a partition, delete a partition, etc.) . You do not need to choose
- to create partitions on the second hard disk. The boot flops will figure
- out whether you were using it.
-
- (3) At the screen asking you to choose between non-destructive/destructive
- installation, choose (1) for non-destructive install.
-
- (4) Insert the third floppy when prompted.
-
- (5) When you see the prompt to remove the third floppy, hit DEL.
-
- (6) You will see a screen asking you to choose between resuming install or
- canceling the installation. Just hit DEL here. You may need to hit it
- a couple times. You should then see a prompt ("#").
-
- (7) Do what you need to do. Note the following:
-
- -- You can now put any floppy you wish into either floppy drive,
- and you should have access to your tape controller if it is
- there.
- -- you have up to 2 serial ports configured in your kernel.
- -- you have no networking.
- -- your root file system is mounted as "/" (as opposed to
- /install or /mnt). Other file systems except /home
- and /tmp are mounted on it. You will need to mount /tmp and /home.
- -- you should be able to run standard editing commands (like vi)
- since all libraries will be available to you.
